摘要
采用硝酸一过氧化氢消解试样，电感耦合等离子体发射光谱法测定儿童发样中铝、钙、铬、铜、铁、钾、镁、锰、钠、铅、镍、锌等十二种微量元素。方法回收率95％-105％，各元素检出限（ug／mL）在0．0010-0．011之间，相对标准偏差（RSD，n=9）小于4％，经人发国家一级标准物质验证，测定值与标准认定值无明显差异。
This paper uses the nitric acid and hydrogen peroxide aluminum, calcium, chromium, copper, iron, potassium, magnesium, other trace elements in children＇s hair by inductively coupled sample sodium, digestionarticle, plasma atomic emission Determination of nickel, zinc and spectrometry.The recovery rate of 95%-105% ,The detection limit of element （ug/ml） in 0.0010-0.011 ,The relative standard deviation （RSD, n=9） is less than 4%,After verification of human hair in national standard reference samples, The measured value had no significant difference with standard value.
